Writer-director Roskam's impressive debut Bullhead (aka Rundskop) is a bleak, dense, complex thriller set in rural Belgium where rival farmers and criminals from both the Walloon and Flemish communities are involved in the trafficking of illegal hormones for the enhancement of livestock. Matters come to a head when a cop investigating the trade is murdered, an undercover police unit penetrates this underworld, and suspicion spreads across the countryside. The unusual settings range from a small-town red-light district to a harness-racing stadium, and the clever plotting connects a terrible event 20 years earlier to the current crime. "There's no such thing as coincidences, they're for losers," a female cop comments, and the link provides a central metaphor of corruption through the steroids fed to the cattle and the ones taken by the eponymous "Bullhead". He's Jack Vanmarsenille (a frighteningly convincing performance by Matthias Schoenaerts), a vulnerable, uncontrollably violent Flemish peasant right out of Zola.
